هُوَ ٱلَّذِى جَعَلَ ٱلشَّمْسَ ضِيَآءً وَٱلْقَمَرَ نُورًا وَقَدَّرَهُۥ مَنَازِلَ لِتَعْلَمُوا۟ عَدَدَ ٱلسِّنِينَ وَٱلْحِسَابَ ۚ مَا خَلَقَ ٱللَّهُ ذَٰلِكَ إِلَّا بِٱلْحَقِّ ۚ يُفَصِّلُ ٱلْـَٔايَـٰتِ لِقَوْمٍ يَعْلَمُونَ
It is He who made the sun a radiance and the moon a light, and ordained its phases that you might know the number of years and the calculation [of time]. Allah did not create all that except with justice. He elaborates the signs for a people who have knowledge.
